1 / 6ATS Dual Power Switch
63A 4P Automatic Transfer Switch 110V/220V - PC Class 50ms Three-Phase+N ATS for Commercial Use
The ATS-W2R-4P is a PC class (load level) automatic transfer switch for three-phase systems with neutral (3L+N), rated at 63A and supporting both 110V and 220V AC. All four poles 鈥?three phases and neutral 鈥?switch simultaneously in 50ms, ensuring complete isolation between sources and eliminating any risk of backfeed. When Source A (mains) fails, the unit instantly transfers the load to a generator or PV inverter; once mains is restored, it automatically reverts to Source A priority without manual intervention. Supports both automatic and manual switching modes to suit diverse installation needs. Built on a motor-driven mechanism housed in a PA6 flame-retardant enclosure, the W2R-4P combines three-phase coverage with neutral switching 鈥?essential for balanced load distribution in commercial and medical environments such as hospitals, cold-storage facilities, and data centers.
